Electric throttle control actuator consists of throttle control motor, throttle position sensor, etc. The throttle position sensor responds to the throttle valve movement.
The throttle position sensor has two sensors. These sensors are a kind of potentiometers which transform the throttle valve position into output voltage, and emit the voltage signals to the ECM. In addition, these sensors detect the opening and closing speed of the throttle valve and feed the voltage signals to the ECM. The ECM judges the current opening angle of the throttle valve from these signals and the
ECM controls the throttle control motor to make the throttle valve opening angle properly in response to driving condition.

DTC DETECTION LOGIC

NOTE:If DTC P2135 is displayed with DTC P0643, first perform the trouble diagnosis for DTC P0643. Refer to See: P0643.

DTC CONFIRMATION PROCEDURE1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following before conducting the next test.

Check the voltage between electric throttle control actuator harness connector and ground.

Is the Inspection result normal?
YES >> GO TO 3.
NO >> Repair open circuit, short to ground or short to power in harness or connectors.3.CHECK THROTTLE POSITION SENSOR GROUND CIRCUIT FOR OPEN AND SHORT

Also check harness for short to ground and short to power. Is the Inspection result normal?

YES >> GO TO 5.
NO >> Repair open circuit, short to ground or short to power in harness or connectors.5.CHECK THROTTLE POSITION SENSOR
Refer to Component Inspection.
Is the Inspection result normal?
YES >> GO TO 7.
NO >> GO TO 6.6.REPLACE ELECTRIC THROTTLE CONTROL ACTUATOR
